N'ITED STATES PATENT SIMON J. HARRY, OF NEGAUNEE, MICHIGAN.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 273,357, dated March 6,1883.

Application filed January 18, 1883. (No model.)

To all whom it may concern:

Be it known that I, SIMON J. HARRY, a citizen of the United StatesofAmerica,residing-at ings, and to letters or figures of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements incar-couplings; and it consists in providing the draw-head with a slidingpin-support, which is attached to the same in longitudinal grooves, andprovided with a spring which abuts against thepin-support and the rearof the draw-head, the drawhead being also provided with perforations forthe reception of the coupling-pin, which perforations are of differentdiameters, the lower one being larger than the upper, the aforesaidelements being utilized in'combination with a coupling-pin having itslower end or point of a greater diameter or thickness than the body ofthe pin, the coupling-pin also being provided with a removable head,whereby the same is prevented from being withdrawn from the draw-head,as will be hereinafter more fully set forth, and pointed out in theclaims.

,In the annexed drawings, which illustrate my invention, Figure l is aperspective view; Fig. 2, a vertical section, and Fig. 3 a verticaltransverse section.

A represents-a draw-head, which is attached to the cars in theusual'manner, and it is proyided at its central portion, in the rear ofthe link-receptacle, with a perforation, B,in which is placed a suitablespring, b. Forward of this opening the draw-head is provided withguideways a c, which extend longitudinally on the sides of the same, ona line slightly in frontot' the vertical perforations. One of theseguideways, 0, is attached to the coupling-head, so as to be removabletor the insertion of the pinsupporting plate D, which pin supportingplate, when the coupling-pin is raised, is forced,

by means of the spring b, to the front ends of the guides c c. To insertthis pin-supporting plate the removable side 0 is taken off and theplate D inserted, as will be fully understood from the accompanyingdrawings. This draw-head is also provided with perforations E E, whichare located near the front of the draw-head, in the usual position.These perforations are of different diameters, the lower one, E, beingof a greater diameter than the upper one, E, for the purpose as will behereinafter more fully set forth.

F represents a coupling-pin, the lower portion or point of which isenlarged, as shown atf, and it is provided at the opposite end with asuitable eye, in which is inserted a ring, 0. Beneath this eye the upperpart of the coupling-pin is screw-threaded for the reception of the nutg; or it may be perforated for the reception of a spring-key, as shownat g in Fig. 3. When it is desirable to insert the coupling-pin withinthe draw-head, the nut g is removed, as well as the ring e,'and it ispassed through the perforations E and E.

The nut is then attached to the upper part of the coupling-pin, and theringinserted,whereby the parts are firmly united to each other, andthere is no danger of the coupling-pin fall-. ing out or beingdisplaced.

I am aware that prior to myinvention coupling-pins have been attached tothe draw-heads, so' that they could not be removed from the same; buttheconstruction of the parts to attain this end has been complicated,and has consisted in some cases ofvariously-constructed pins, which areheld in place by means of movable plates attached above the draw-heads,and guides secured .to the .upper part of the same; but I do not claimsuch construction,

broadly.

The operation of my invention is as follows: When it is desirable tocouple cars the pin F is raised, as shown in Fig. l, the enlarged end fpreventing the same from being withdrawn from the draw-head, and thepin'rests upon the link-support D. When in this position thecoupling-pin cannot be displaced by the jar when the cars come together,as is often the case when pins of ordinary construction are used, andwhen the cars abut against each other the link strikes against thepin-support D and drives the same backward, allowing the pin to fall andembrace the link.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupling device, the draw-head A, provided with perforationsE E, of different diameters, in combination with a couplingpin having anenlarged end,]", and removable head, substantially as shown, and for thepurpose set forth.

2. In combination with a car-coupling device having a slidingpin-support and vertical openings, one of the openings being of greaterdiameter than the other, a couplingpin having a point of less diameterthan the lower opening and ofgreaterdiameter than the upper opening, andaremovable head, substantially as shown.

3. In a car-coupler, a transverse pin-support, operating in longitudinalguides or grooves, and a removable side, 0, substantially as shown, andfor the purpose set forth.

In testimony whereof I have affixed my signature in presence of twowitnesses.

SIMON JAMES HARRY.
